I'm looking to upgrade my stock 6.00-6 Aero trainer tires that came with the Kit (IV 1200). I have the Matco W62 split rims. Dôes anyone have any advice or opinion to share on a good "Tundra" tire that isn't too terribly big ? I've been looking at the Aero classic ribbed 21/800-6's but don't know if that's a good choice. I only fly off grass and the ground is always either rock hard-bumpy or soft-mushy throughout the year. I'm also thinking about getting a Matco WHLT-8WD dual fork tailwheel to replace the stock Maule. Is that a good idea ? It's pretty wide and a bit heavier than the Maule ?
